Attach wheel wrench and with the
jack correctly aligned rotate wheel wrench until wheel is clear of the
ground.
6. Unscrew the wheel nuts. 7. Change the wheel. Spare wheel 3 262.
8. Screw on the wheel nuts.
9. Lower vehicle.
10. Install the wheel wrench ensuring that it locates securely and tighten
each nut in a crosswise
sequence. Tightening torque is
150 Nm.
11. Align the valve hole in the wheel cover with the tyre valve before
installing.
Install wheel nut caps.
12. Install vehicle jacking point cover.
13. Stow and secure the replaced wheel 3 262, the vehicle tools
3 251 and the adapter for the
locking wheel nuts 3 69.
14. Check the tyre pressure of the installed tyre and the wheel nut
torque as soon as possible.
Have the defective tyre renewed or
repaired as soon as possible.

Spare wheel Some vehicles are equipped with a
tyre repair kit instead of a spare
wheel.
If mounting a spare wheel, which is
different from the other wheels, this
wheel might be classified as a
temporary spare wheel and the
corresponding speed limits apply,
Page 265 of 327

Vehicle care263even though no label indicates this.
Seek the assistance of a workshop to
check the applicable speed limit.
The spare wheel has a steel rim.Caution
The use of a spare wheel that is smaller than the other wheels or in
combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
The spare wheel is located in the load
compartment beneath the floor
covering.
To remove:
1. Open the floor cover.
2. The spare wheel is secured with a
wing nut. Turn wing nut
anticlockwise and remove the
spare wheel.
Under the spare wheel there is the box with vehicle tools.
3. When, after a wheel change, no wheel is placed in the spare wheel
well, secure the tool box by
turning right back the wing nut and close the floor cover.
Stowing the replaced full size
wheel in the spare wheel well
The spare wheel well is not designed for all permitted tyre sizes. If a wheel
wider than the spare must be stowed
in the spare wheel well, the thread
bolt for mounting the wheel must be
replaced by an extension bolt, located
in the tool box 3 251. To replace the
bolt:
● Remove tool box from the spare wheel well.
● Install the hexagon key of thewheel wrench ensuring that it
locates securely on the bolt.
● Turn the wheel wrench anticlockwise to loosen the bolt.
Remove the bolt.
● Take the extension bolt from the tool box 3 251 and screw it in
hand-tight using the hexagon key of the wheel wrench.

264Vehicle care
● Store the tool box and thedamaged wheel outside up in the
spare wheel well and secure it by turning the wing nut clockwise on
the bolt.
The floor cover can be placed on the
projecting wheel.
To fit the spare wheel in the well after
renewing the defective wheel use the
short thread bolt again. Exchange the
bolt in the same way.
9 Warning
Storing a jack, a wheel or other
equipment in the load
compartment could cause injury if they are not fixed properly. During a sudden stop or a collision, looseequipment could strike someone.
Store wheel, jack and tools always
in the original storage location and secure them by fixing.
Temporary spare wheel
Caution
The use of a spare wheel that issmaller than the other wheels or in combination with winter tyres
could affect driveability. Have the defective tyre replaced as soon as
possible.
Only mount one temporary spare
wheel. Do not drive faster than
50 mph. Take curves slowly. Do not
use for a long period of time.
If your vehicle gets a flat tyre on the
rear while towing another vehicle,
mount the temporary spare wheel in
the front and the full tyre in the rear.
Tyre chains 3 257.
Directional tyres
Fit directional tyres such that they roll in the direction of travel. The rolling
direction is indicated by a symbol
(e.g. an arrow) on the sidewall.
The following applies to tyres fitted
opposing the rolling direction:
● Driveability may be affected. Have the defective tyre renewed
or repaired as soon as possible.
● Drive particularly carefully on wet
and snow-covered road
surfaces.
